Performance analysis of digital communication systems

The advanced communication technology, which is considered here, stems from spread spectrum, error correction coding, and waveform modulation techniques. Communication efficiency, design flexibility, and high jamming resistance of a communication system are enhanced by fully utilizing three available resources: time, frequency, and code. Because the coding scheme should be analyzed in conjunction with the signal design to determine the tradeoffs between different coding/modulation schemes, a unified, analytical technique is developed. The developed technique is demonstrated in this paper to compare the performance attainable in several digital communication systems and to evaluate various coding schemes
